Immunologic Tolerance - 2
•1.Tolerance to Self-antigens - continued
•L B-lymphocytes
•Nmature in bone marrow
•Nlack of THelper cell stimulation
•Nthose that react with self-antigens are eliminated by clonal abortion
•Ncan be induced to nonreactivity creating a state of anergy (unresponsiveness).
•2.Tolerance generated during an immune response
•L Four mechanisms that induce tolerance
•Nclonal exhaustion
•Nanti-idiotype antibodies
•Nfeedback inhibition
•NTSuppressor cells
